To (LZZ whom, it 7nay concern. Be it known that I, CHARLES C ARENCE Po LE, a citizen of the United States, and a.

r ldent of Evanston, inthe county of Cook 'vandState of Illinois, have invented certain new and useful Improvements in Paper.- Movement Indic'ators'for Type-Writers; and

I do herebydeclarethat the following is a-full,'

clear, and exact description-thereof; reference being bad to the: accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to-a novel indicatorfor use on type-writercarriages and designed more especially to indicatejthe extent to which the plate should be tli-rned backward inafter st forth, and-more particularly point'-.

by hand for admitting new sheets when mak mg carbon copies of a number of writings onbon copies.

- The invention consists in the matters hereed out in the appended claims.

proved indicator applied thereto.

ln'the drawings, Figure -1 is a perspective View 'ofthe right hand end of a paper car riage, showing the platen therein and my irn- Fig. 2 .is

As shown in said drawings, A indicates the platen or paper-roller; B theright-hand end plate'of the paper-carriage in which the shaft a "of the platen has bearing Cand D 5 the paperguides on the carriage; E, the upperlongitudin-a1 frame-bar of the carriage; one of the end paper-guides mounted on said frame-bar E; G, the upper guide-roller of the'carriage,

and 'H the scale-strip located above the platen adjacent to said' guide-roller. platen-shaft a has at its outer end a turning knob or disk A; saidknob A beingifastened to the shaft by means of a sleeved, fixed to the shaft by a screw a a The parts above described correspond with those used at present in the Qliver type: 7. writing machine, in which the type-levers are located above the platen and the'types strike downwardly upon the upper surfacethereof;

the carriage-frame, which coacts indicates a rotative member having the general form of a disk andcarrying an index finger or pointer J; It is mounted on the vplaten-shaft inv a manner to, be locked to the shaft to turn therewith and also tobe released therefrom to turn thereon. Saiddisk is provided, as herein shown, with circumfere ntially-spaced graduations or scale-marks,

dex-finger J on the. disk I.

L designates an index finger or ointer which is mounted on and turns with t e disk I and is also adapted to be turned 'or rotated dex-finger J, so as to be laced at varying an-; gular distances from sai fingerJ. Means are about the disk-axis toward and from the inprovided for locking said indicator L in any adjusted position.

The disk I is provided'on its, outer face with a huh I, through'whieh the platen-shaft extends and in which it has bearing, and

said'disk is held from endwise movement'on' the shaft between two fixedoollars A A on the shaft, the latter being contained Withina recess atthe outer end of the hub. Said disk I-isad-apted to be locked to the platerbshaft in such manner as to-rotate therewith when the shaft is rotated; but preferably and as hereinshown the disk is normall free on the shaft and does not turn therewith. In the present instance the diskI is automatically returned to its startin position when released from the shaft a wit the pointer J in line with the stationary pointer .Such automaticreturn of thedisk is conveniently effected by gravity. In other words, said disk is eccentrically weighted, so that when'it 'is 1 free to rotate 'on the shaft the gravity of such eccentric weight acts 'to bring the ndicator to the upper part of the disk or inllinewith the indicator or ointer K. The may beconnecte with the disk I orshaft a pointer L by any suitable means adapted to retain the same in position inwhieh it may be placed with respect to the pointer- J on the disk,

while, enabling said pointer L tobe-readily' I I shaft.

shifted when desired. In the present embodiment of my invention the pointer L is mounted directly on the disk I.

Referring now to the details of construe-- tion in the features above referredto'and illustrated in the drawings, the same are made as follows: The disk I is'mounted on the platen-shafta. outside of and adjacent to the end plate B of the carriage-frame.

Said disk is normally free to rotate about the shaft (1. The gravity-acting means for returning the disk to its startin position and for holding it in such ositlon consists, as herein shown, of a weig t I that is fixedto and extends laterallyfrom the outer side of the disk,

the part I being ofsuch Weight as to reliably bring the disk to rest with the weight-always at the lowermost part of the disk. The disk is locked to the shaft awhen it is desired to rotate the disk with the shaft by any suitable positively-acting locking means, as a clutch device one member of which rotates with said Said clutch device is made as follows: The outer'end of the hub I of the disk I is provided with'spur-teeth which engage like teeth formed on the adjacent end of the sleeve M, that is free to slide endwise on the shaft (1, but is nonrotative thereon.

Said

' sleeve M is provided-at its outer end with a radial flange m, having preferably a knurled periphery, whereby the sleeve may be readily grasped by the fingers to operate the same The sleeve is held non-rotative on the shaft,

,while permitted to slide endwise thereon, by

. at both limits of its movement, w ereby the, clutch member of the sleeve is held positivel fromthe high point thereof,

engaged with the clutchmember of the hu or is positively held in its releasing position. A simple locking device for effectingthis'resuit is shown in the drawings and is made as follows: The shaft (1 is.prov1ded-with a longitudinal recess a}, in which is located a short leaf-spring a that is atlixed at one end thereof to one endof the bottom of said recessand is raised at its other end out of eontactwith the other end of the recess-bottom. The free or raised end of said spring a is-engaged by the inner end of a screwstud m which extends radially through the sleeve M. Said spring is provided .just inside of the ou-ter or freeend with an angular or inverted-V shaped projection, it 'inclinin both ways en the stud engages one angular side of. said 'proj ection, it holds the clutdh-sleeve fromjm'ovement in one direction, and when it engages the other side of said projection it holds the sleeve from leasing position.

movement in the opposite direction. When, therefore, the clutch-sleeve M is in its innermost position and the ,disk is therefore clutched to the shaft, the inner end of said screw-shaft e engages thespring rejection inside the highest part thereof, and therefore prevents thesleeve from, sliding outwardly and the release of the clutch. This position of the parts is shown in Fig. 3. When the. clutch-sleeve M is shifted outwardly and the clutch released, Fig. 1 the stud m rides over the highest part of the projection. and engages the outwardly-inclined part thereof, whereby the sleeve is positively held in its re Such form of clutch device is desirable when used with a disk or other indicator carrying device that is automatically returned to' a predetermined position, inasmuch as the said disk or the like is normally free on the shaft and need not turn therewith. The pointer L, which is mounted on and turns with the disk I and which is adapted to be angularly shifted or adjusted with respect to the indicator or pointer J of said disk, is

formed, as herein shown, upon the periphery go of a plate L, that is provided with a central aperture and mounted on the shaft 0, and

' bears against the flat inner face of the disk I.

The plate L is loekedto the disk by means of a clamping-screw L that extends loosely through anannular slot i in the disk I, concentric' with the axis thereof, and has serewthreaded engagement at, its inner end with an aperture in a peripheral lug lot the plate L,

as shown more clearly in Fig. 4. WVhensaid clam ing-screw L of the plate L is released, the'p. ate is free to be rotated on the shaft for changing the angular distance between the ointer L, carried thereby, and the pointer J hefore referred to. After such angular adjustment of the pointer L has been effected the clamping-screw is ti htened to clamp the plate L against the dish, and thereby maintain the adjustment of the pointer L.

The indicating-disk is preferably provided with an annular-peripheral surface, on which are formed the graduations or scale-marks referred-toij-so that such graduations. and the numbers appliedthereto may be readily ob-- served by the operator, and the indicator J on said disk is located at and constitutes the zero-mark of such scale, which, as before stated, when the disk is free 'on the shaft is held, by the weight I in line with the pointer or indicator K.

The 0 eration of the indicating device describe will be understood from the following: The general urpose of the paper-movement-indicating eviee is to indicate to the operator the extent of angular movement of the platen required when inserting a sheet of paper into the machine in order to bring the first line of printing a desired distance from the top margin of the paper according to the space occupied by the heading on thesheet.

record-stri ,butat uniform distances apart or'with equal-spaces between the set of reco ords or copies-,,land the line-indicating device.-

is employed toenable the operator to readily insert a new sheet for each separate original manner that the ,first printed line of the carbon copyshall belo- 5 cated at adesired distance from the last printediline of'jthe'precedin carbon copy,

while at the same time the first line of the original bill or invoice will comewith certainty in o to margin of the sheet on which said ori na bill record-strip and a sheet of paperfor the ori 'inal bill or invoice has been inserted into t e machine with a 'carbon-paper between the 5 -same,'the'first bill or invoice maybe rinted, and thecarbon-copy will be made in t e usual manner on the record-strip The printing of ,the bill or invoice havingbeen completed,

Y the platen will then'be turned to carry the i o erator locks the disk- I to the original sheet out of platen then turned backwardly to move or shift'the-record-strip backwardly to such a i w point that when thenewsheet is inserted the.

In using'the indicating device as described forithe purpose of deterbackwardly. the operator sets to turn the :platen backwardly after printing the last. line of one original bill or invoice'in ordegjto start a new ,or original sheet in the.

In cases proper position with respect to the or invoice is printed. Assuming t epointer L has been adjusted an the machine and the p of the'carbon copy as -.to .le ave 'a desired space on therecord-strip sheet.

first original and carbon sheets is effected while theoriginal sheet'is in place in order to determine the extent of the backward movement required to enable the printi'ng'to be started on theneXt succeeding original bill 'withthe' proper spacebetwen the copies on the'carbon sheet or strip. The platen is now allowed pointer the-manner described until it is posite to the fixed ointer K. ,Theangular distance between t times that the platen must be turned backwardly after the'printing of each original sheet to bring the copy of the next blank original sheet at the desired distance from the 'copy of the preceding ori inal sheet andfiat the same time affords the esired spacing between the copies of the carbon-sheet. The device has now been adjusted for invoicesheets having heads of the use of the device .for printin d locked in such' adjusted position relatively to the pointer J the printing of each invoice is completed in the usual manner, and on the completion of the last line thereof or after the printed original has been removed the disk I is locked to the shaft with the pointer J opposite thefixed pointer K. turned backwardly, carryin' with it the disk I and pointers J and L, unti the pointer'L is opposite to the stationary pointer K. A

newsheet of paper is now inserted into the machine in the usual manner, and the platen is thereafter turned forwardly to carry the e pointers J and L willthen correspond with and indicate the dis-- certain width, and in.

after the to remain in this position, while the. L is angularly adjusted on the disk in The platen is then 'roc record-sheet in position for printing, which position is determined on the new original It follows, that by the' use of the, de-

vice describedthe operator having once cle- I termined the angular distance or number of line-spaces whic the platen must be turned backwardlyforstartinga new sheet in every instance or-when inserting each new original sheet for an original bill or invoice he invariably turns the (platen backwardly the same distance, accor g'to the angular distance between the pointers J and L, and will thus be able to invariably brin the firstrinted stance from the last-printed line on the record-sheet,

therehly leaving uniform spaces between the I severa copies of the record-sheet, ,Moreover, the o erator is'able to locate-the carbon copies on t e record-sheet as closely to ether as desirable without danger, on the one and,

of bringing the carbon copies to ether or in overla pin relation and without iability, on the ot er Trend, of se arating the carbon "copies on the record-s eetso widely as to waste space on said record-sheet.

The I are mainly useful to enable the pointer L to' graduations or scale-marks on the disk p .1 0

be set in a desired osition for original sheets having headings of diiferent widths without any test to determine such position when the operator has previously ascertained and knows from recollection the-s aces on. the

.be done by merely shifting the pointer L baekwardly or forwardly one or more spaces desired. It will be observed, therefore, that the graduations onthe disk I have no function to perform in the usual operation of the disk or wheel, the only parts coming into use at such time being thepointer K on the frame and the fixed and adjustable pointers J and y L, respectively, on .the disk, the angular distance of which latter from each other determine the distance through which the platen .is to be turned backwardly in inserting each new sheet.

While the disk I is shown as having a projecting part forming the pointer J, yet the same results will be obtained by providing said disk with a, score-line or zero-mark'for pointer as used in the the scale. Moreover, the stationary pointer K may be replaced by a mark or score-line on the end plate of the carriage-frame.

From what has been heretofore stated it is understood that the term indicator or a pended claims is intended to be as well a isk provided with an indicating-mark or score-line or a part of or upon the carriage-frame having such mark or score-line, as a projectin part, arm, or index-finger, the parts referre to equally performin the functions of an indicating means to etermine the line'-s ace position of the platen or the extent to w 'ch it is turned.
